Affinity Designer Questions

I noticed in the Microsoft store it says as long as you are logged in with your Microsoft account, you can install Infinity Designer (bought through the Microsoft Store) on up to 10 devices. I can’t find anything in the Serif store. Does anyone know this???

I know that YouTube has a great Illustrator tutorial series (I posted one I found) with a complete gammat of things to learn along with free downloadable worksheets. Has anyone found something similar for Affinity Designer?

I have time right now to really learn this — or learn Illustrator but I need to settle on one. I do NOT like that Adobe went to online monthly/yearly charges but that is where Affinity might replace it. I started a tutorial quite awhile back in Affinity (but it was lacking) and gave up due to not enough time. would really like to make use of this time and increase my skills.

Anyone switch from Illustrator (mine is CS3 and is buggy) to Affinity and wish they hadn’t? Why?

Thanks for any information!
